TENNIS-COURT MARKER.

Application filed May 25, 1926. Serial No. 111,606.

vide such a marker which is easy to fill and assemble and which is extremely efiicientin its operation. i

Another object of the present invention is the provision of such a marker including a plurality of hollow cylindrical sections together with new and novel means for securing said sections together.

I Another object of the invention is to provide such a marker .having incorporated therewith new and novel means for retaining the sections out of contact with the ground whereby to effectively prevent the clogging of the openings through which is sifted the lime orthe like used for marking the court. A further object of the present invention is the provision of improved means for guiding the marker which will result in the making of perfectly straight marking lines.

A still further obj ect; of the present invention is to provide such a marker which is simple in construction, strong,sturdy and durable, one which is efiicient and effective in its operation, one which can be-manufactured at a small cost and placed on the market at areasonable figure.

WVith these and numerous other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be more fully'herein'after described, illustrated in the accompanying drawings and particularly pointed out in the appended claims.

In the drawings forming a part of this application and wherein like charactersof reference denote corresponding parts thro'ughout'the several views: Figure 1 is a top plan View of a marker constructed inaccordance with the present I invention.

Figure 2' is a side view thereof. Figure 3 is a central longitudinal sectional view through the marker sections.

Figure '4is a transverse sectional view taken on line 44 of Figure 3 looking in the direction of the arrows.

Referring now more specifically to the accompanying drawings wherein for the purpose of illustration has been disclosed a preferred embodiment of the present invention, it will be seen that the present 1111* proved marker comprises in its construction a major section 10 and a minor section 11 associated therewith, the major section 10 including an elongated hollow cylinder 12 over which is telescopically received the cylinder 13 of the section 11. The cylinder 12 is provided intermediate its ends and immediately adjacent the inner end of the cylinder 13 with an annular series of openings 14.

The outer ends of the sections 10 and 11 are provided withthe disc plates 15 and 16 respectively, it being noted that the said plates project beyond the cylinders and are provided with the inwardly directed annu la-r ground engaging flanges 17 and 18. These flanges serve to prevent the cylinders from coming into contact with the ground,

thereby preventing the clogging of the siftlng openings 14 by dirt and the like.

Carried by the end plates 15 and 16 are the knobs 19 and 20 respectively provided with the trunnions 21 and 22 which receive the ends of the resilient supporting arms 23 and 24, the resiliency of these arms serving to securethe said sections together relative to'one another. The supporting arms 23 and 24 are curved rearwardly and inwardly and the arm 24 is secured to the arm 23 as indicated at 25 while the said .arm 23 is extended laterally to provide a guide loop 26 formed with the laterally directed terminal guide hook 27. Suitably secured to the guide loop 26 is a flexible element 28 by means of which the marker may be pulled over the tennis court or the like.

In the use of the present invention, a guide rope or the like 29 is first stretched across the tennis court where it is desired to mark the same. The marker is then positioned as shown in Figure 1 so that the guideloop '26 will engage the guide rope 29. As the marker is then pulled along by means of the flexible element 28, it will be guided by the said guide rope which will result in the making of a perfectly straight line. Should. the supporting arms 23 and 24 be pulled upupwardly, the hook 27 will engage the guide rope 29 thereby preventing the loop 26 from becoming entirely disengaged from the guide lGO rope 2t). qXs the marker la pulled along, the dry lime or the like contained therein will be, sil'ted through the openings 1 1-.

hen it is desired to refill the marker with. lime or the like, the resilient arinsilil and 24.- are pulled outwardly and disengaged from the trunnions 21 and a'tler whioh the (yiinders 1.2 and 13 an be 1 iadily se iaratml and the lime "an then be placed within the cylinder 12. The partsjare then assen'ibled by placing the eylinder 13 over the cylinder 12 and engaging the arms 23 and 24 with the trunnions 2L and .lt will be noted upon re l'erenee to Figure 2:) that when the oeelions are in assembled position, the lniler end of the e yliuder 1:2 abuts the inner surlace oi the disc plate Ill.

l roni the foregoing, it will bi readil appreciated that there has been prorided a novel and simplified marker which will aetoinlilish all. oi. the objected-int perform all of the Functions enumerated as being desirable in the statenu' iit oi the invention set l'orth abo\' and it is to be llh'ilvlrl'tmll that various changes in the details o'l eoi'istruelfiOll may be resorted to without departing from or exeeoding the spirit of the inventioln so lone as sllt'll changed fall within the seope ot the appended claims.

\Vhat claimed in:

1. A marker of the eha 'aeter described, comprising a pair of telescoping sections, one of said sertions being provided with an annular series oi: openings intermediate its ends, dise plates carried by the outer ends of said sections, tttt'll. havinp an annular inturned ground engagingllange lornled integrally therewith and resilient means earriml by said dise plates for securing said sections together. i
